Ipolymeric methylene diphenyl polyol isocyanate i-diisocyanate iyinkqubo elizenzakalelayo kwiimbali zokuhlanganiswa kwezinto eziningi. Iinkqubo enye eyayixhaswa ngokulandelana nge-polyurethane, inyongo esiqinileyo eseyenza iiplasitikhi yamandla evulekileyo esetshenziswa kumanyange okukena. Leli nkcwadi liqinisekelayo kunjalo kunjalo kwaye liphumeleleyo ngokukubona ukuthi ligcinikiwe ngeminyaka engaphambi. Liyafuna izindlela ezininzi eziqondisiweyo, njengesayithi, olungena kuhlanganiswa kwamakhi ya nezintloko zakhi, kunye nokuthengisa, olungena kuhlanganiswa kokubhedelela amaxhovha kunye nezinto zakho.
Polymeric methylene diphenyl polyether polyols uDiisocyanate ungenzi ngezinto ezininzi. Ungayibuyisela ukwenzela amathuluzi esebenzisa amacushion okufuneka kusithathelane, okanye ungayibuyisela ukuba yileyo yezityhili lokugcina uhlangothi lokusebenza ngokubonakalisekileyo nokuhlala phakathi kwesikhatsi sokuthi abantu bazofuna ukukhululeka. Ukuya kusebenzisa ukuba zizama izicatulo — imigomo ephakeme — i-adhesive — umlayo omkhulu ongazama ukubuyisela izinto zimaphandle — kunye ne-sealants — ezinamandla ukubuyiselana ngemihla kunye nokugcina amagqwaba.
Polymeric methylene diphenyl Pu amaphu zokungqinisekisa uDiisocyanate, usetyenziswa ngokuphakamisayo nokuphakamisayo. Leli nqanawa liphumelela ipolimeri we-polyurethane ngezinto ezininzi ezilungileyo ezifanelekayo ngazo kwiindlela eziningi. Ngokuvamile, xa icimenti usebenzisa kuhlanganiswa, ungayibuyisela ukuba lexicatulo singazama ukwenza ukuthatha ukudlula emva kokuthi amagama angahlala phakathi komhlaba obungaphezu kwezindlu ezidingekileyo. Kwesikrini, ukuya kusebenzisa ukuba zingazame ukwenza amaxwebhu amandla kweziqhuthu ezilandelayo kunye nokubuyisela kakhulu.
Ipolymeric methylene diphenyl diisocyanate inguqu phakathi kwezindawo zokugqibela nokusebenza lokuncedisi. Kwindawo yokugqibela, isimo ngaphandle siphatha ukwenzakanisa amandla nokuhlala ekunye kwezinto ezincedwe. Usebenzisa, ngokushesha, ukuze ifake amaxhobo apha esihlangene ngephandle kwemiseko yobukheli bese elinye ilizwe lokufika lokusala okanye lokungathathwa emva kokusekelayo. Usetyenziswa ngenxa yesi sicelo sekhohlwa ukufaka amaxhobo angaphinde akhutshwe indlu. Ipolymeric methylene diphenyl diisocyanate usebenziswa kwindawo yokusebenza lokuncedisi ukwenza amandla amaphantsi lokusebenza abafanele baye basebenzela ngamandla kunye nokulula. Leli lihlobo lesi sicelo selikhoyo lokuncedisi xa kulula ngokuthi liphakamile kunye nokuhlala ekunye kwezinto ezincedwe. Liyabonisa ukuba le nto ibaluleke ukuba zingene nezinto eziphathelayo zingavumelekanga.
Ipolymeric methylene diphenyl diisocyanate iyinto elikhulu lokusetyenziswa kwiqhutywa lwezilungileyo, amandla-aphandle, nokulandelela. Ngenxa yezilungileyo, ingxenye yahlala ukuba imisebenzi yokuvumelanisa imibuzo engavumelekanga ngokwesintu esidingayo kwindawo yokugcina, futhi umoya omkhulu noma omncedisi wakwesphendulo. Ukuphathelwa kwezindaba ezimbili zemakheli eziphuma emanzini Kukho kuhlu lokuncedeka lokuhlala kanye nokusebenza phakathi kwezindlela ezinomsindo. Ngokubanzi, le nto inceda ukuba izindlela zihlale zikhona ngexesha elinganayo, futhi ngokushesha ngokuphindaphinda, ngokufanele kungene okanye umoya omkhulu noma umncedisi wakwesphendulo. Ipolymeric methylene diphenyl diisocyanate iyinyekezo elikhulu lokuncedeka ngoba iyusetshenziswa kwiqhutywa lesi sisekelo, lokhu kungena ukuba yinto elithunyelwe kulesi sisekelo sokusebenzela. Ingcwadi enkulu yalo ngamaxesha angasetshenziswa ngazo zonke izinto esizivumelana nazo zonke izinto ezazisebenzela kumhla woqala.
